NWS NEXRAD Level 3 Radar (Composite Reflectivity) with Storm Cell Tracking
The strongest returned energy for each elevation angle in a volume scan is compiled into one image called, simply, composite
reflectivity. Whereas the base reflectivity image is the first image available during a volume scan, the composite reflectivity image
is one of the last views necessitated by the need for all elevation scans to be completed before this image can be produced. Best
at determing storm structure and strength.

NWS NEXRAD Level 3 Radar (Storm Relative)
When the motion of storms are subtracted from the wind field, the result is a picture of the wind as if the storms were stationary.
As in the case of all velocity images, red color indicates wind moving away from the radar with green color indicates motion
toward the radar. (The radar is located in the center of the image.) Small scale circulations, from which tornadoes often form,
will typically be indicated by strong inbound wind located beside strong outbound wind relative to the radar.
